The meiting points and boiling points of two isomeric alkanes are as follows: CH3(CH2);CH3, mp = -57 °C and bp = 126 °C; (CHalsCC(CH3)3, mp = 102 °C and bp = 106 °C. (a) Explain why one isomer has a lower melting point but higher boiling point. (b) Explain why there is a small difference in the boiling points of the two compounds, but a huge difference in their melting points.

Below are structural formulas for isomers of butane. What type of isomerism is exemplified by these isomers? What makes (a) cis- and (b) trans-?

Draw and name the seven constitutional isomers (i.e., all contain a ring of some size) for cycloalkane, C,H12.

Draw all possible structure(s) and give the IUPAC systematic name(s) of an alkane or cycloalkane with the formula C8H18 that has only primary hydrogen atoms...
